Vibratory Centrifuges for Coal
TEMA Vibratory Coal centrifuge
2 Mass vibration system, consisting of:
- Small Mass:
.Screen basket, Inlet pipe, shaft and bearing housing
- Large Mass:
-Product housing, Cross member, Steel frame
- In-between the 2 masses are rubber buffers
- The vibrations are generated by 2 counter rotating unbalance weights.
- This gives vibration in the resonance range, somewhat less then natural vibration. The amplitude of the empty machine can be set by adjusting the pre-tension on the rubber buffers.
- When the feed is increased the load in the basket increases, increasing the small Mass, thus giving a vibration coming closer to the natural frequency. This automatically increases the amplitude.
